Worker A's 0x800F4B88 (128 B, first attempt) -- its eighth epilogue-class row and its last.
158: two type views over the same halfwords are DELIBERATE. The first helper call loads with lh
(signed) and the second with lhu (unsigned) over the SAME pointer, so the source declared a
short* view for one expression and an unsigned short* view for the other. Writing the whole row
as short* gives lh for the second call too and changes the bytes. When one function reads the
same field both ways, the mixed lh/lhu pair over one pointer is the evidence.
